With the ability to recognize up to 4,096 levels of pressure and low latency, the S Pen becomes a tool for users who regularly take notes, sketch or work in the creative and design fields.
Even if you're not a designer, artist, or regularly take handwritten notes, the S Pen still offers a host of practical benefits.
Realize every idea from drawing
With the help of Galaxy AI on the Galaxy S25 Ultra, anyone can easily bring their ideas to life. Use the S Pen to draw a simple sketch in Samsung Notes, then select the “Sketch to Image” feature, users can turn their rough handwriting into a complete image in a variety of styles, from cartoons, sketches to illustrations.

Users can also quickly activate this feature as soon as they pull out the S Pen without having to open the Samsung Notes app. This is an intuitive, time-saving way and is very useful for those who do creative work, need to record and develop ideas immediately.
AI Select understands and analyzes the screen the user is viewing
AI Select on the Galaxy S25 Ultra is an intelligent assistant that can recognize what is displayed on the screen and suggest appropriate actions. For example, when the user selects an address, AI Select can immediately suggest directions to it, or suggest saving it to contacts if it detects a phone number.

For text, users can quickly access Galaxy AI tools such as rewriting in a different style, summarizing content or translating. For videos , AI Select supports converting to GIF images, making it easier for users to share interesting moments in a more vivid way.
Additionally, users can edit photos more precisely with Generative Edit and Object Eraser. Users can edit photo composition by adding or removing unwanted objects, while still maintaining harmony and naturalness thanks to the processing power of Galaxy AI.

When combined with the S Pen, these features become significantly more effective, especially in photos of large groups of people or many small details. Instead of using your finger to draw an area, users can use the S Pen to precisely mark each border, helping Galaxy AI identify the correct part to edit and minimize the risk of mishandling the image area.
Sign and annotate documents and texts
There will be times when users need to sign a document such as an employment contract, a house lease, or administrative procedures, but not everyone has a drawing board or specialized equipment available to digitize signatures.

The feature not only allows signing but also allows users to take notes and mark directly on text files, a useful application for both work and study (Photo: Samsung).
With the S Pen on the Galaxy S25 Ultra, users can sign directly on the phone screen, edit if needed, and export files as PDFs. This is a suitable tool for those working in the business sector, needing to process documents quickly anytime, anywhere.
Tons of other useful tools in the Air Command menu
Every time you remove the S Pen from the Galaxy S25 Ultra, you can quickly access the Air Command menu - a collection of useful tools for many different situations. These are features that are not used every day, but are convenient when needed.
For example, the Translate feature allows users to instantly translate any word or content on the screen by simply moving the pen tip to that location. A specific situation is when traveling , users can use it to translate restaurant menus, even convert currency units to local currency. The Magnifier feature is also a valuable tool, especially when users need to view details of maps, documents or small text.

In the context of the new flagship product line such as Galaxy Z Fold7 prioritizing thin and light design, Galaxy S25 Ultra becomes the only high-end phone model that still retains the S Pen. This is the unique point that makes Galaxy S25 Ultra a worthy choice for those who need a versatile device, comprehensively supporting both work and creativity, when accompanied by Galaxy AI.
